This Product Selection Guide contains information to help select products in the Ultrasonic Receivers, Transmitters category on DigiKey.com
Ultrasonic Receivers and Transmitters are designed to detect and transmit high frequency sound waves, respectively. They are characterized by frequency, rated voltage, and beam angle. Their typical operating frequency range are 50Hz, 10kHz to 65kHz, 20kHz, 25kHz, 28kHz, 38kHz to 42kHz, 40kHz, 42kHz, 49.5kHz, 58kHz, 60kHz, 300kHz, 1MHz, 2.45mHz, and 168MHz.
SelectionCharacteristics
Specifications to determine which ultrasonic receiver or transmitter is right for your application.
Frequency: The specific frequency or range of frequencies that the sensor is designed to transmit and/or receive.
Voltage - Rated: Typically this represents the maximum voltage rating to which a device will meet its given specifications. Exceeding this voltage rating may damage the device and other system components.
Beam Angle: Describes geometry of a device’s region of sensitivity or transmission focus.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
